What Makes Red Bank's Water Unique?

Local geology and source profile

Source: ReservoirTDS: 485.5 mg/LpH: 8.3

Red Bank, New Jersey, in Monmouth County — a Monmouth County borough adjacent to Shrewsbury and Rumson on the Navesink River in northeast New Jersey — receives its water from the New Jersey American Water, drawing from Manasquan Reservoir (Monmouth County) through the northeast New Jersey distribution.

The hard 181.5 mg/L hardness and TDS of 485.5 mg/L reflect the northeast New Jersey Monmouth County Manasquan supply's hard calcareous character — similar to Eatontown NJ (151.5/368.9) in the same Monmouth County on the same supply, Red Bank is slightly harder reflecting the distribution end position with greater calcareous accumulation (compare Fair Haven NJ: 145/358 in Monmouth County softer; Red Bank harder at the Navesink River corridor). The Manasquan system at Monmouth County — Cretaceous Raritan Formation (slightly calcareous — primary hardness contributor), Pleistocene Atlantic Coastal Plain sand (insoluble — dilutant), and Quaternary Navesink alluvium (calcareous — TDS contributor).

At 181.5 mg/L with TDS 486, Red Bank's water is hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 13.1 ppt is very high — a certified drinking water filter with PFAS removal is strongly recommended — the Monmouth County northeast New Jersey military and industrial corridor contribute to Red Bank's very elevated PFAS readings.

Geology & Source: Red Bank in Monmouth County is served by New Jersey American Water drawing from Manasquan Reservoir — the Manasquan watershed drains Cretaceous Raritan Formation (slightly calcareous) and Pleistocene Atlantic Coastal Plain sand (insoluble) — NJ Monmouth County Manasquan Cretaceous coastal plain supply produces hard water at 181.5 mg/L with TDS 485.5 mg/L.
